' DEVICE FOR EXPANDING FELLIES.

SPECIFICATION forming part of Letters Patent No. 463,206, dated November1'7, 1891.

Application filed February 12, 1891- Serial No. 381,13. (No model.)

To aZZ whom it may concern.-

Be it known that we, GEORGE R. THOM- SON and HARVEY T. OoTTRnLL, ofGouverneur, in the county of St. Lawrence, in the State of New York,have invented new and useful Improvements in Devices for ExpandingFellies, of which the following, taken in connection with theaccompanying drawings, is a full clear, and exact description.

Our invention relates to devices for expanding fellies or rims ofwheels.

Our object is to produce an easy and convenient device whereby thelength of the spokes between joints may be increased, thereby expandingthe fellies or rims thereon.

Our invention consists in the several novel features of construction andoperation hereinafter described, and which'are specifically set forth inthe claims hereto annexed.

It is constructed as follows, reference being had to the accompanyingdrawings,in which- Figure 1 is an end view of a land-roller in which theexpander is used. Fig. 2 is a longitudinal section thereof through thecen- 2 5 ter, showing an axle upon which the same is mounted; Fig. 3 isan end view of the expanding hub with the spokes removed. Fig. 4 is aside view thereof, with a part of the outer casing cut away, showing thespokes resting 0 in the slotways upon the inner head of the hub. Fig. 5is a section thereof on line X X, Fig. 4. Fig. 6 isa View of the outerend of one of the spokes, showing the tenon entering the rim or .felly.

Similar letters of reference indicate the corresponding parts.

A is a hub consisting of two parts 1 and 2. The part 1 consists of abase 3 and a frustoconical head l, erected thereon and havinga 4ocentral opening 5, through which an axle B passes. The outer peripheryof this frustoconical head 4 is provided with any desired number ofslotways or recesses 6, for the purpose hereinafter setforth. The part 2of the 5 hub consists of a disk having a central opening, through whichthe head 4 may pass, an annular flange 7, in which are slotways 8 orholes corresponding with the slotways 6 in the head 4. Through theslotways 8 or holes 53 and into the slotways or recesses 6 We insertwheel consisting of a hub constructed in two the inner ends of thespokes of the wheel, as shown in Fig. 4 of the drawings, and these twoparts 1 and 2 of the hub are secured together by bolts 9. The outer endsof the spokes enter and are secured to the rim in 55 any ordinary andwell-known manner.

It will be observed that the lengths of the spokes between joints may bevaried by adjusting the two parts of the hubs 1 and 2 with respect toeach other, which causes the inner ends of the spokes to traverse theslotways in the frusto-conieal head 4:.

I It will thus be'seen that if we desire to expand the rim of the wheelit will simply be necessary to tighten up the nuts upon the bolts 9,which will force the inner ends of the spokes up the slotways in thefrusto-conical head. It will further be observed that with variations tosuit the device the same principle may be applied to any kind of a wheelwhere it is desired to expand the rim.

It will be seen that the base 3 of the male section will enter under theflange 7, and that this flange will thus perform the function of adust-band and keep the dust and dirt, as well as a large part ofmoisture, out of the hub, and that this is a veryimportant function.

' What I claim as my invention, and desire to secure by Letters Patent,is-

1. A device for expanding the rims of a Wheel, consisting of a hubconstructed in 'two sections, one of which has a base and afrusto-conical head, said head having vertical slot-ways, the othersection of which has a disk with a central opening and provided with anannular flange, said flange having openings or slotways adapted to fitover the aforesaid section, means for securing the said section togetheradjustably, spokes passing through the openings in the flange andresting in the slotways upon the aforesaid head, as set forth.

2. The combination, in a land-roller, of a sections, one of which has abase and a frus to-conical head, the other section of which has a diskwith a central opening and pro vided with an annular flange, said flangehaving openings or slotways and adapted to too fit over the aforesaidsection, means for sei In Witness whereof We have hereunto set curingthe said section together adjustably, our hands on this 22d day ofJanuary, 1891. spokes passing through the openings in the GEORGE E.THOMSON. flange and resting in the siotways upon the HARVEY T.
